Would people really buy a 2000 toyota corrola engine? What would be its worth? at 100k miles?

$500 or so. There are alot of parts that will sell, some you wouldnt think of. Little trim pieces. Transmission is a big one. Lights, doors, window glass. Rearview mirrors. If you do it right you will basicaly have to scrap the frame. Though be careful or you will have to drag that out of the garage lol.
